Technician Bypasses Laptop EEPROM Supervisor Password
While refurbishing a customer's laptop, YouTuber and hobbyist onionboots disabled an administrator BIOS supervisor password by shorting the mainboard EEPROM's reset pin. He later found the password reappeared because keeping the pin shorted prevented writing the new supervisor-password state to EEPROM. The correction to an online guide shows a simple stop-short technique saves time versus brute-force cracking, including attempts aided by LLMs.
Key Points
- 1Shorts EEPROM reset pin to disable BIOS supervisor password on a refurbished laptop.
- 2Reveals continuous shorting prevents writing new password state, causing password to reappear on reboot.
- 3Implies technicians should release the short during write phase to persist password changes and save time.
